Memorial diamond made from ashes or hair of the loved one

High quality and noble diamonds are made entirely of carbon. Since the human body also contains 18% carbon, the noble LONITÉ diamonds are made from the carbon found in hair, cremated bones or cremation ashes. The following overview provides information on the price, quantity and size of the diamonds made from ashes.

6 months on average

The diamond burial in Germany and Austria is certified and the resulting burial diamonds are real.

The only difference between a natural diamond and that of a LONITÉ diamond burial is its origin: the carbon of the diamond from ashes is obtained from human cremation ashes, while the natural growth takes place with the help of underground, carbon-containing minerals.

From light yellow (left) to deep orange (right), each diamond burial has an individual color.

Grown naturally

A unique form of burial

Each diamond has grown naturally and is completely unique - just like the loved one during their lifetime, no two diamonds are the same.

The final shape, size and color of the funeral diamond made from hair or ashes depends entirely on the origin of the raw material. The decisive factor is the composition of the carbon.

After the hair and cremation ashes for the diamond from ashes have been received by us in Switzerland, they are cleaned and placed in a synthetic environment. Here they can grow into a diamond independently and without external influences.

This environment only gives a tendency for the size of the diamond made from ashes. The exact dimensions can neither be controlled nor predicted. This form of burial remains something very special.

In this way, a diamond burial creates an irreplaceable and unique diamond made of hair or ashes, which is absolutely extraordinary not only in its origin, but also in its appearance.

Diamond burial sizes

Diamonds are generally measured in carats (Kt), a unit of mass.

One carat is equal to 0.2 g (200 mg; 0.007055 ounces).



[*] The preview of the sizes may differ from the actual dimensions due to different screen resolutions.
The size of the memorial diamond is influenced by the specified growth time for the diamond burial.

Rough diamonds are not cut to preserve their natural appearance.

Cut of a commemorative diamond

Natural beauty

A burial diamond in the rough is a unique choice for those who prefer complete naturalness and want a "whole" diamond that has not been stripped. Please note, however, that only cut diamonds have the famous 'brilliance'. In addition, the colors of rough diamonds can appear darker.

Rough diamonds (uncut / uncut) are available at a discount of 20% for sizes from 0.35 carats. A rough diamond for diamond burial in Austria and Germany is unfortunately not possible for 0.25 carats.

The right shape for diamond burial

You can choose from 10 different cuts for your very own memorial diamond.

The cuts differ mainly in their brilliance. In general, however, one can say: the more corners and cuts the diamond has, the higher its brilliance.

For this reason, as its name suggests, the brilliant cut is the one with the highest brilliance and also our most popular cut.



You don't know which cut is the right one?

No problem! You can simply leave the cut option blank on the diamond burial order form. The cut is then determined by our experts according to the final shape of the funeral diamond.

So you don't have to choose the shape, because the diamond does it by itself.

In this way, as little as possible of the diamond is abraded and a large part of its volume is retained - this also applies to diamond burials in Germany and Austria.

Color variations of a diamond

7 unique colors for your diamond burial in Germany and Austria

Naturally grown diamonds are born with a number of different colors due to the diverse, underground environments, it is very different with diamond burial.

Unfortunately, in our synthetic environment, we cannot make this wide range of colors possible for a diamond made from ash (Switzerland). However, we can create different colors as the memorial diamonds grow.

With the help of the body's own elements contained in the ashes, we can create 7 unique colors. Since the effort involved in manufacturing varies depending on the color, this also has an impact on the costs of diamond burial. Here are some color samples of the cost of a diamond made from ashes.

The creation of the colors for a commemorative diamond

Natural Amber ™

The human body consists of 3% nitrogen 1429, which gives the diamond its natural Amber ™ color.

Natural amber ™ is therefore the color that is achieved in the standard process for Swiss diamonds from ash - without adding or removing any other substances, ash turns into a diamond.

Each diamond made from hair or ashes has its own natural color (from light yellow to dark orange). No two color nuances are exactly the same in this form of burial.

Purely Colorless ™

In order to grow a pure colorless ™ diamond, the nitrogen 1429 has to be removed from the carbon [C] of the ashes.

This process is very complex and time-consuming, which also explains the higher diamond burial costs for pure colorless ™ diamonds.

But they convince with the highest carbon purity and the noblest appearance.

Additional colors

Apart from the two variants shown above, the other colors are achieved through different chemical or physical environments, as shown below. This also results in different prices for diamond burials.

Certificate of authenticity of the funeral diamond

Memorial diamonds are real diamonds that can be certified by all globally recognized gemology institutes.

The proof for eternity: an independent proof

The certificates of authenticity for LONITÉ diamonds can be obtained from Gemological Institute of America (GIA) or International Gemological Institute (IGI), which prove that all LONITÉ diamonds are real diamonds and certify that they are artificially produced (not mined).

The origin of your commemorative diamond from the LONITÉ laboratory is proven in the certificate.

After the burial diamond has finished growing, a third-party certification can be requested from the GIA or IGI to ensure the authenticity of your memorial diamond and, above all, to identify the diamond's origin - the LONITÉ laboratory.

The barcode is attached to the container for all intermediate steps. Tracking ID, name and dates are logged in accordance with our Standard Operating Procedures (SOP) - LNT OT95000: 2010.

Always by your side

We understand your worries and fears, and we know that it is not easy for you to give up the remains of your loved one.

So that you always know how far your diamond from ashes has already progressed in Switzerland, you will receive reports from us at regular intervals on the progress of the burial.

You can also contact our competent service around the clock, who will answer any questions you may have about your diamond.

Make your diamond even more individual

... with laser marking

You can add a name, date of birth or maybe even the coordinates of your meeting to your memorial diamond.

The finished gemstone can be personalized with words, numbers or even short sentences in memory of the funeral. The desired characters are then engraved on the edge of the diamond.

Transparent and comprehensible: our service for you

Photos are taken of every key step in creating your memorial diamond.

Track every step

Sending your loved one's ashes for a Swiss diamond burial can be a very emotional event. It is therefore very important to us that you feel as involved and connected as possible. For this reason, we will send you photos of the process of making your diamond burial at regular intervals.

This is a wonderful way to be step by step and to experience the change.

Be there at the diamond burial

Some of our customers send us a photo of their family together with the ashes before the diamond burial so that this family picture can then be shown on all photos of the intermediate steps of the memorial diamond. LONITÉ is more than happy to be able to fulfill these wishes in order to add a meaningful and personal touch to the diamond burial.

ID tracking

I. Maximum use of ashes / hair for a diamond burial

Up to 99.99%.

It would actually be wrong to say that "a memorial diamond is made from 100% ashes" ✘.

For a diamond burial in Austria and Germany, a microscopic diamond is always required as a so-called seed crystal, from which the commemorative diamond for this form of burial can develop.

However, LONITÉ is able to produce memorial diamonds that are made up of up to 99.99% of the carbon from human ashes or hair.

II. Natural diamond seed crystal

No artificial CVDs for diamond burial

A Diamond seed crystal is a microscopic diamond that serves as the basis for the memorial diamond that grows from it. The carbon atoms (from the ashes / hair) then attach themselves to it under enormous pressure and begin to crystallize.

As a diamond seed crystal, LONITÉ only uses the best 0.1% single-crystal natural diamonds instead of CVD diamonds (Chemical Vapor Deposition).

III. A special type of diamond: IIb

Valuable and unique

The LONITÉ diamond burials in blue and colorless ™ are Type IIb diamonds.

You can recognize them by the following procedure: When examined with an infrared spectrometer, these diamonds show a remarkable absorption of the red color of the visible spectrum.

This type of diamond occurs in nature only 0.1% and is therefore very rare and valuable. LONITÉ's type IIb diamonds are visually indistinguishable from the natural variant.

And best of all: The type IIb commemorative diamonds have a much more valuable origin than the natural diamonds of this type - because they come from your loved ones.

IV. No heavy metals (0.00%)

100% sure

LONITÉ diamonds are free from lead (Pb), mercury (Hg), bismuth (Bi) and sodium bromide (NaBr).

LONITÉ also uses natural and medically safe means to clean the ashes for a diamond burial.

No heavy metals (0.00%) are used in the entire LONITÉ production process.

V. No artificial colors (0.00%)

Natural colors only

The Swiss company LONITÉ makes colored diamonds from ashes by providing you with a special growth environment instead of mixing artificial colors into the diamonds.

The artificial environment only provides a basis for the coloring. The final color then depends on the composition of the substances in the ash.

Each diamond made from ashes has a unique color that emerges from the ashes. No two diamonds are alike.

VI. Absolute purity (4N)

The essential 99.99%

The production of diamonds from ashes via the high pressure high temperature (HPHT) diamond synthesis can only be effectively achieved with the purest forms of carbon. All other trace elements must be removed.

Therefore, the ashes must be cleaned, because impurities lead to diamond defects and can split the diamond crystal.

Carbon is the basic element of life that occurs in every body. In order to avoid any defects, the purity of the carbon in the LONITÉ diamond burial is at least 99.99%.

VII. 18% and 3% of the human body

Positive life elements

Carbon [C] occurs in the human body in a proportion of 18%; Nitrogen 1429 is 3%. Both are important building blocks for proteins (with amino acids) and DNA. Without carbon [C] and nitrogen 1429 there is no life.

The carbon purification system leaves either nitrogen or boron (related to the metabolism of calcium) as a base for growth, which creates either an amber or a blue color in the diamond burial.

The diamond burial result, on the other hand, will be Purely Colorless ™ if only the carbon is retained and all other elements are removed.

LONITÉ diamond burial is a
✔ GIA certified real diamond
✔ HPHT diamond burial
(High pressure high temperature)
✔ New diamond made exclusively from ashes
✘ Imitation diamonds: moissanite or zircon
✘ CVD diamonds (Chemical Vapor Deposition)
✘ Off-the-shelf diamond injected with ashes

✔ LONITÉ IS a GIA certified real diamond burial.

A LONITÉ memorial diamond made from hair or ashes is physically, chemically and visually similar to a naturally mined diamond.

LONITÉ's real diamonds have a refractive index of 2.419 and are therefore the same as naturally obtained diamonds.

✘ NO diamond imitation: jewel, crystal, zircon.

An "imitation diamond" is a fake diamond that is not made with carbon. Zircon (ZrSiO4) is a mass product for fashion jewelry and low-priced clothing accessories.

A fake diamond has a refractive index higher or lower than 2.419, which means that both brilliance and brightness are very different from a real diamond. If ashes are refined into diamonds, the result has a refractive index of 2.419.

✔ LONITÉ is an HPHT diamond.
(High pressure high temperature)

The carbon source of LONITÉ's HPHT diamond burial is pure carbon powder from ashes (in a solid state).

The high-pressure, high-temperature process is based on the same principles as the natural production of diamonds and takes several months. During this time, the ashes can be pressed into diamonds.

✘ NO CVD diamond
(Chemical Vapor Deposition)

The carbon source of CVD diamonds is a hydrocarbon gas such as methane.

The ongoing process only takes a few hours, but uses many, many cubic meters of additive gas to provide the necessary carbon.

✔ LONITÉ is like a newborn diamond.

Your memorial diamond made from ashes or hair is a completely new diamond that has been artificially grown.

The required diamond seed crystal is only 0.01%. 99.99% of the diamond for this form of burial grows from the real elements of the deceased.

✘ NO diamond burial that involves injecting ashes through a hole.

Some high-priced "diamond burials" in Germany and Austria are nothing more than drilling an existing diamond and then inserting a tiny amount of cremation ashes into it.

Heavy metals such as lead (Pb) and bismuth (Bi) are used in this procedure for "diamond burial". At LONITÉ, real ashes are pressed into diamonds.

Pour les diamants commémoratifs, les couleurs ambrées et dorées sont les options les plus basiques. Ces diamants sont produits selon une procédure simple, sans ajouts de microéléments ni de traitements techniques spéciaux. Les coûts et les durées de production des diamants commémoratifs ambrés / dorés sont les plus réduits, ce qui fait que ce sont les plus popular. La color ambrée / dorée résulte naturellement de l'azote qui reste dans le carbone et qui est essentiel dans les corps humains composés de protéines et d’ADN.

Le diamant commémoratif vert / jaune a besoin d'un cycle de traitement HPHT supplémentaire afin de modifier la structure cristalline ainsi que les centers colorés du diamant. En conséquence, la couleur verte / jaune nécessite un temps de fabrication plus long et a un prix relativement plus élevé.

Les diamants commémoratifs rouges obtiennent leur belle couleur en utilisant le même procédé qu’avec les diamants ambrés / dorés, mais avec un processus plus approfondi. En appliquant une lumière d'électrons à haute énergie avec un émetteur électronique, des centres colorés libre d'azote se formeront à l'intérieur du diamant ce qui donnera au diamant sa color rouge.

Le diamond commémoratif bleu parait majestueux et paisible. LONITÉ possède une technologie de pointe permettant de déterminer la densité d'atomes présente à l'intérieur des diamants commémoratifs. Ainsi, the color of diamonds bleus LONITÉ est très equilibrée. La croissance du cristal est plus rapide et plus facile lors de l'introduction d'atomes de bore à l'intérieur du carbone, ce qui fait que non seulement la production est plus rapide mais aussi que le coût est plus bas par rapport aux diamants commemoratifs incolores.

Le diamond commémoratif incolore est caractérisé par la pureté carbonique la plus élevée et ne présente aucun autres éléments ni impuretés. De plus, la procédure de production d’un diamond blanc pur est la plus technique et la plus onéreuse car sa production requiert plus de temps.
